The 1985 Toyota Supra Turbo represents a pivotal moment in automotive history, marking the arrival of a sports car that seamlessly blended everyday usability with serious performance. While the first generation Supra, derived from the Celica, was available with a naturally aspirated inline-six, the 1985 model year introduced a turbocharged variant that captured the imagination of enthusiasts worldwide. This specific model year sits at the intersection of emerging Japanese technology and the growing demand for affordable performance, creating a legacy that remains potent decades later.
The Birth of the A70 Supra
Unveiled in late 1982 for the 1983 model year, the A70 Supra broke away from its Celica roots to become a distinct model. By 1985, the lineup had been simplified, with the naturally aspirated 5M-GE engine being phased out in many markets in favor of the more potent turbocharged version. The 1985 Toyota Supra Turbo, often referred to as the "Supra Turbo," was powered by the 3.0-liter 7M-GTE engine, a robust powerplant that combined the reliable architecture of the 5M with a turbocharger and intercooler. This evolution resulted in a significant power increase, making the car a formidable performer on both the street and the quarter-mile strip.
Engineering the 7M-GTE Engine
The heart of the 1985 Supra Turbo is the 7M-GTE, a 2,954cc inline-six cylinder engine. This unit featured a single turbocharger, mounted in the valley of the V-shaped configuration, which fed pressurized air to each bank of cylinders through a front-mounted intercooler. The intercooler was a crucial component, cooling the compressed air to increase its density and, consequently, power output. The result was a healthy 145 horsepower and 185 lb-ft of torque, figures that were impressive for the mid-1980s and provided strong mid-range punch that made the car feel quick in everyday driving.
Performance and Driving Dynamics
Power delivery is one aspect, but harnessing it is another, and the 1985 Supra Turbo excelled in this regard. The turbocharger provided a broad and usable power band, eliminating the need to dwell in the upper RPM range to access performance. This characteristic made the car exceptionally practical, transforming it into a comfortable grand tourer that could also entertain. The rear-wheel-drive layout, combined with a well-tuned suspension and available Torsen limited-slip differential, ensured that power was transmitted to the road efficiently, offering a stable and planted feel even during aggressive cornering.
Acceleration: Official 0-60 mph times hovered around the low 7-second range, a testament to the efficiency of the turbo system.
Top Speed: A governed top speed of approximately 130 mph was electronically limited, though evidence suggests the car was capable of more in the hands of a skilled driver.
Fuel Economy: Despite its performance orientation, the efficient 7M-GTE could return respectable mid-20s MPG on the highway, making it a viable daily driver for those who treated their car with respect.
Exterior and Interior Design
The 1985 model year brought subtle but important visual cues that distinguished the Turbo from its naturally aspirated siblings. The most obvious was the addition of a prominent hood scoop, which fed cool air directly to the intercooler and turbocharger. The front fascia featured a unique mesh grille, and the rear was complemented by a subtle decklid spoiler that helped maintain high-speed stability. Inside, the cabin was a sanctuary of Japanese luxury, featuring bolstered leather bucket seats, a three-spoke steering wheel, and a dashboard dominated by easy-to-read gauges, all designed to keep the driver informed and engaged.
